ARNOLD C. I IAVES, OF NOROTON, CONNECTICUT.

HORSESHOE.

lSPIEICIIEICATI'0N forming part of Letters Patent No. 280,816, dated July 10, 1883. Application led anuaryl 30, 1883. (No model.)

To a/ZZ whom t may concern:

Be it known that I, ARNOLD C. Hiiwns, a citizen of the United States, residing at N oroton, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Horseshoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to horseshoes, and has for `its object to form a light and exceedingly durable shoe, one that can be readily, and without the employment. of skilled labor, changed from smooth to sharp, or the sharp calks, if worn smooth, may be removed and new ones substituted, while at the same time it shall be simple in construction and economical in cost.

With these ends in view my invention consists in a base-plate about half the thickness at its edges of an ordinary horseshoe, which is provided near its outer edges with the usual grooves and holes for the nails, it being intended to be attachedl in the same manner as an ordinary horseshoe. Vithin the lineL of nail-holes, and at the' toe of the shoe, are one or more depressed panels an eighth of an inch (more or less) in depth. rlhese panels extend nearly to the inner edge of the plate, a narrow raised strip or bead only surrounding the depression. One or more strips or cross-pieces may be used, making, in fact, a number of separate panels. My invention also consists in a top plate having the usual calks at heel and toe, which is similar in general construction to the base-plate; and, finally, my inventionY consists in the combination and peculiar mode of attaching the two plates together, all of which will be hereinafter more fully described, and specifically designated by the claims.

In order to enable those skilled in the art to which my invention appertainsto make and use my improvement, I will proceed to describe the same, referring by letters to the accompanying drawings, forming part of this specication, in whichl A Figure I is a plan view of the top plate 5 Fig. 2, a plan view of the base-plate; Figs. 3 and 4, side elevations of the above parts respectively; Fig. 5, aside elevation of the two plates united, showing the screws in dotted lines; Fig. 6, a

sectional view on line a: x of Fig. I, and Fig. 7 is a sectional View on line 1/ y of Fig. l.

Similar letters indicate like parts in the several iigures of the drawings.

A is the base-plate, and B B are depressions or panels therein. a is a raised strip or bead of metal surrounding the depression. b b are cross pieces or strips, which serve additionally to brace and strengthen the base-plate, and d d the usual nail-holes for attaching the plate in place, the same as an ordinary horseshoe. C C are internally screw-threaded bosses, which project above the surface of the surrounding strip or bead a distance just equal to the depth of the depression in the top plate.

A is the top plate, whosedepressions BB,

raised strip or bead a', and cross pieces or strips b b correspond in location with the similar parts in the base-plate. The top plate is furthermore provided with holes c c, which register with the bosses C C in the base-plate. The said holes c c are countersunk, so that the screw-heads will lie iiush with the surface of the top plate. The screws may be made of any suitable metal; but a non-corrosive metal or alloy-such as copper or phosphor-bronzeis deemed preferable.-

It will be observed that the construction I have described will make the shoes exceedingly light, which is an advantage in use and a great saving in the amount ci' material required, while at the same time the amount of p material actually used is so disposed of as to give` the maximum of strength and durability. The raised beads and the cross-pieces in the two parts register with each other, thereby giving solidity equal to a solid shoe. The

ybosses also add to the rigidity of the shoe, as

they bear against the sides and bottom of the depression in the top plate. The depressions are aboutan eighth of an inch (more or less) in depth, thus making the hollow spaces in the centerof the shoes approximately a quarter of an inch in diameter. I do not oi' course confine myselito any particular kind of metal, but contemplate using malleable cast-iron or dropforged steel for one or both plates. A very cheap and serviceable shoe results from mak,- ing both plates of malleable cast-iron and the calks alone of steel, or the entire upper plate may be made of drop forged steel and the IOO base-plate of malleable iron. In practice I contemplate that the base-plate shall be nailed in place by a skilled workman in the usual manner, after which any person may attach the top plate, or exchange one top plate for another in the event of the top plate wearing out, or of its becoming desirable to have sharper calks, thus avoiding the necessity of going to a blackslnithshop and waiting for hours to get a little work done in the event of a freezeup; or if it be desirable to change to a very light upper plate for trotting it can be done without diiliculty, and afterward a heavier plate can be replaced. The base-plate need not be touched until the growing out of the hoof renders triinining necessary. In actual practice I have found both base and top plates in excellent condition more than thirty days after putting onto a horse having daily use.

I ain well aware that duplex shoes are not broadly new, and therefore make no claim to them; but,

Having described my invention, what I do claiin as new, and desire to secure by Letters Patent, is

1. A horseshoe made in two parts, each of which has two or more depressions or panels surrounded by raised beads, and having crosspieces which register withl each other, whereby hollow spaces are formed in the interior of the shoe.

2. In a horseshoe, the base-plate A, having depressions B B and bosses C C, in combination with plate A', having depressions B 3', and screw-holes c c, which register with the bosses, substantially as and for the purposes' set forth.

In testimony whereof I affix my signature in presence of two witnesses.
